Reconstructing evolutionary rates from age-structured phylogenies

Reconstructing rates of speciation and extinction from molecular phylogenies has been difficult and some might say questionable. ┬áIn this project I’m exploring how clades diversifying in age-structured landscapes (like volcanic islands or rift lakes with known chronologies) could provide a space-for-time solution to reconstructing rates from phylogenies. By adding immigration to standard birth-death models I’ve been able to link between and within island (or lake) diversification rates an am working on the resultant likelihood method for reconstruct meaningful, and statistically reliable, rates of speciation, extinction and immigration.
